[ahonn]

• GraphQL API modules basic struct
• implement latestBlocks query and block model/resolver
• basic Transaction/Cell models
• add block data loader to optimize performance
• integrate CKB RPC websocket
• add RGB++ transaction graphql schema & resolver
• integrate Mempool.space API and electrs
• add Bitcoin transaction graphql schema & resolver
• auto generate graphql schema file
• dockerfile and compose file

NOTE:

• For the convenience of development, database modules are not imported for the time being
• The model structure of the GraphQL layer follows the previous database table structure as much as possible
